NEAL s. MCLAY, or QLATHE', KANSAS. Lamm Paten: No. 85,841, dated Jmmwy12, 1869 IMPROVEIHENT LAND-ROLLES.

The Schedule refer-:edm in these Letters Patent and making part of thesame.

the county of Johnson, and State of Kansas, have inventeda new anduseful Improvement in Land-Rollers; and I do hereby declare that thefollowing is a full, clear, and exact description thereof', which willenable those skilled in the art to make and use the same, referencebeinghad to the accompanying' drawings, forming part of thisspecification, in which- Figure 1 is 'a top orvplan view of my improvedroller.

Figure 2 is a` detail'vertical section of the saine, taken though theline 2.x, iig. 1.

vSimilar' letters of reference indicate corresponding parts.

Myv invention has4 for its object to finnish an improved land roller",viihichy shall. be. so constructed and arranged that the rollers mayadapt themselves to rough or uneven ground, so that the entire surfaceof said ground may be suitably rolled; and

-It consists inthe construction and combination of various parts of theroller, ashereinaiter more fully described.

'Ais the tongue, which is attached to the frame B'by an ironconnecting-piece, a, an'd which is also strength? ened by the braces a,as shown in iig. 1.

The main or forward-roller-frame B is made rectangular in form, and itsfront and rear side-bars are connected and supported at their middlepoints 'by the long bolt or bar b', es shown in iig. 1.

C are the front rollers or cylinders, the journals of which revolve inbearings in the end of theframes D, v which are made of such a size asto t loosely into the frame B at the Sametime that the rollers orcylinders C fit loosely into them,as shown in gs. 1 and 2.

The frames D are pivoted, at the central points 'of their front and rearside-bars, to the front and rear sidevbars of the frame B, as shown infigs. 1 and 2.

This construction enables the rollers or cylinders C to adapt themselvesto the surface of the ground, should said surface be rough or uneven, sothat all the ground may be suitably rolled.

As thus arranged, there will be a space of a foot, mor or less, betweenthe adjacent ends of the rollers The ground thus left unrolled is rolledby the rear roller E, the journals of which revolve in bearings in theend-bars ofthe frame F, as shown in figs. l and 2.

The middle point of the front side-bar of the frame Fis connected tothemiddle point of the rear sidebar of the frame B, by the connection G, orequivalent connection, in such a. way that the frame F and roller E mayhave a vertical, lateral, and rocking or oscillating movement, enablingthe said roller to adjust itself to the surface of the ground to berolled.

The connection G is constructed as follows:

A small block or roller, g, is p ivoted in a vertical position to earsattached to the middle part of the rear side bar of the frame B, and asimilar block or roller, g2, is pivoted in a horizontal position to earsattached to the middle part of the front side-bar of the frame F.

The blocks or rollers g and g2 are connected to each other by a shortbolt, g3, which should be swivelled to one or both of the said blocksorrollers g g2, so that the said connection may forma universal joint,allowing the roller E and frame F to take any position'that' the surfaceof the ground may require.

The frame F is alsoconnected to the frame B by two chains, H, whichshould be of such a length that when the machine is drawn forward in astraight line, the chains H may both be suiciently slack to allow theroller E to move freely, as the surface of the ground may require.

The chains H are designed to assist in turning the rear roller, and torelieve the swivel-connection from the strain in turning, and should beof such a length as to prevent the frame Ffrom ever coming in Contactwith the frame B when turning the machine.

I is the drivers seat, which is supported from the frame F in such aposition as to be directly over the centre of the roller, thusequalizing the weight. i

Iclam as new, and desire to secure by Letters Patent- 1. Theswivel-connection Gr, constructed substantially as herein shown anddescribed, in combination with the trames B and E, as and for thepurpose set forth.

2. The combination and arrangement of the tongue A, frame B, frames D,rollers or cylinders` C, chains H, swivel-connection G, frame F, androller E, with each other, substantially as herein shown and described,
